...says the man who is
notorious for leaving words and whole phrases out of a verse
What I'd said in that LINKed post was:
"
the FIRST time He appeared "apart from sin" [was]
FOLLOWING His finished CROSS-work
[i.e. after His resurrection!]--though it was numerous appearances, all told), He will do THIS
"a second time... [again [APPEAR-G3807 (passive)] apart-from-sin]"
...and again,
NOT speaking of the "OPENLY MANIFEST BEFORE ALL" (but,
like the FIRST time He did was ONLY TO carefully chosen WITNESSES, Acts 10:41), "[SHALL APPEAR]
UNTO them that look for Him"
(this could be referring "the 144,000" [of whom Paul is a "TYPE"], or to a wider audience... but I don't think it necessarily [and likely DOES NOT] refer to "our Rapture [IN THE AIR]" point-in-time, which would occur even prior TO THAT, meaning, prior to "the 144,000" thing [
thus ("re: our Rapture" event) corresponding to an even EARLIER point-in-time which ALSO FOLLOWED His resurrection... which I went into in another post, so won't go into here--but just to say, the PATTERN HOLDS TRUE 
])
The "SECOND TIME" in relation to what? (what does the TEXT say?)
